TR5/TR250 TR250 wiper switch and motor

In the attached BCF thread from 2006, Rob T stated: "To modify the TR6 switch to work with the TR250 motor, you need to install a power diode across the two connections to the field winding. This should give you the correct effect." I have a 4 connector TR6 wiper switch. Can anyone tell me the details for making this change?.... what power diode p/n or rating, and what are the wiring connections for a 4 connector switch. Thanks!

Also in the 2006 thread, Adrio stated: "
For those watching who have problems with the motor, what was wrong with mine was that the windings on the rotor had become unwelded from the posts that are atached to the comutator. I guess at one point in its history that motor had overheated for some reason (my car cam in boxes so I have no idea of history). The fix was for me to re-tack them back on and all was good with the motor. All I had to do was remove the back cover, then remove the brushes and brush holders to get enough access to affect the repair." If Adrio is still active on the BCF, could you give me more detail on where the loose wires were and how did you know which wires to connect to which poles on the comutator? Thanks! p.s. my Tr250 wiper motor only works in one speed.
